Setting up Pulsoid Desktop OSC allows you to send your real-time heart rate directly into VRChat without complicated setups. Whether you want to share your VRChat heart rate inside the VRChat chatbox or show it directly on VRChat avatar using parameters, this guide will walk you through the configuration process step by step.

Before You Begin

Make sure you have the following ready before starting the setup:

A compatible heart rate monitor (such as a chest strap, arm monitor, or smartwatch).
A registered Pulsoid account.
An active BRO subscription (native OSC features require a BRO subscription).
The Pulsoid Desktop app installed on your PC.
VRChat OSC is enabled.

How to Enable OSC in VRChat

Open the VRChat Action Menu, go to Options, select OSC, and toggle it On. VRChat won't receive any OSC data until this is enabled.

Setup Guide

1. Install Pulsoid Desktop

Download the app from the official Pulsoid Desktop download page, run the installer, and sign in using your Pulsoid account.

2. Connect Your Heart Rate Monitor

Turn on your heart rate monitor, select it in Pulsoid Desktop to pair it, and confirm your live heart rate preview is actively updating inside the app.

3. Open OSC Settings

Click Customize in the OSC section to configure your chatbox text, select parameter presets, and adjust specific output settings.

Option 2: Chatbox Messages

Open the Chatbox tab, enter your custom text template using {bpm} that will automatically be converted to your real heart rate, check the preview, and click Save.
